(d) 972​

Answer 1

a. (y + 3)3

3y + 9

b. (1001)2

(1000 + 1) 2

2000 + 2

2002

Answer 2

Answer:

Step-by-step explanation:

1)

 $3 (y+3)\\= 3 * y + 3 * 3\\= 3y + 9$

2) 1001 x 2

2002

3) ?

4)

  $97^2\\\\= (100 - 3)^2\\\\= a^2 - 2ab + b^2\\= 100^2 -2(100)(3) + 3^2\\= 10000 - 600 + 9\\= 9409$
